PetroTrace Downhole Heating Cables Technologies

PetroTraceTM series-resistance heating cables are used in flow assurance applications when circuit lengths exceed the ratings of conventional parallel-resistance heating cables and a single power source is needed.

Consists of a cut to length, field terminated, three-phase, constant wattage heating cable

Allows for temperature maintenance to 122°F (50°C)

Provides up to 41W/m

Is strapped to the production tube, typically to depths of 2625 ft (800 meters)

Can go as deep as 3610 ft (1100m)

Mineral Insulated (MI) Technology

Mineral insulated heating cable is ideal for heavy oil recovery applications where high power and high exposure temperatures are required to increase oil mobility and production in reservoirs. PetroTrace MI cable:

Allows for temperature maintenance to 900°F (482°C)

Provides up to 656 W/m

Comes in different sizes and power levels to provide flexibility for use in flow assurance and bottom-hole temperatures in lengths to 3,037 ft (1200m)

Is typically strapped to the production pipe using clamps or channels

Skin-Effect Heat Tracing Systems (STS) Technology

Typical oil recovery applications for PetroTrace STS are in high producing wells (>5000 BOPD), where heat input is required for flow assurance, most commonly paraffin and hydrate prevention in deep wells (longer than 2000m).
It is also applicable in heavy oil wells that require temperature maintenance along the wellbore for production enhancements or recovery from shutdowns.

This heating cable consists of a coiled tube that contains an insulated conductor inside the tube. Both the conductor and coiled tube are used to form an electric circuit that can provide heat for many kilometres. The STS heater:

Allows for temperature maintenance to 300°F (149°C)

Provides up to 150 W/m

Enables easy deployment without the need for a work-over rig, minimizing installation costs
